/><hr /><h2>Detailed Description</h2><p>The QComboBox widget is a combined button and popup list.</p>
<p>A QComboBox provides a means of presenting a list of options to
the user in a way that takes up the minimum amount of screen
space.</p>
<p>A combobox is a selection widget that displays the current item,
and can pop up a list of selectable items. A combobox may be
editable, allowing the user to modify each item in the list.</p>
<p>Comboboxes can contain pixmaps as well as strings; the <a href="qcombobox.html#insertItem">insertItem</a>() and <a href="qcombobox.html#setItemText">setItemText</a>() functions are
suitably overloaded. For editable comboboxes, the function <a href="qcombobox.html#clearEditText">clearEditText</a>() is provided, to
clear the displayed string without changing the combobox's
contents.</p>
<p>There are two signals emitted if the current item of a combobox
changes, <a href="qcombobox.html#currentIndexChanged">currentIndexChanged</a>() and
<a href="qcombobox.html#activated">activated</a>(). <a href="qcombobox.html#currentIndexChanged">currentIndexChanged</a>() is
always emitted regardless if the change was done programmatically
or by user interaction, while <a href="qcombobox.html#activated">activated</a>() is only emitted when the
change is caused by user interaction. The <a href="qcombobox.html#highlighted">highlighted</a>() signal is emitted
when the user highlights an item in the combobox popup list. All
three signals exist in two versions, one with a <a href="qstring.html">QString</a> argument and one with an <tt>int</tt>
argument. If the user selects or highlights a pixmap, only the
<tt>int</tt> signals are emitted. Whenever the text of an editable
combobox is changed the <a href="qcombobox.html#editTextChanged">editTextChanged</a>() signal is
emitted.</p>
<p>When the user enters a new string in an editable combobox, the
widget may or may not insert it, and it can insert it in several
locations. The default policy is is <a href="qcombobox.html#InsertPolicy-enum">AtBottom</a> but you can change
this using <a href="qcombobox.html#insertPolicy-prop">setInsertPolicy</a>().</p>
<p>It is possible to constrain the input to an editable combobox
using <a href="qvalidator.html">QValidator</a>; see <a href="qcombobox.html#setValidator">setValidator</a>(). By default, any
input is accepted.</p>
<p>A combobox can be populated using the insert functions, <a href="qcombobox.html#insertItem">insertItem</a>() and <a href="qcombobox.html#insertItems">insertItems</a>() for example. Items
can be changed with <a href="qcombobox.html#setItemText">setItemText</a>(). An item can be
removed with <a href="qcombobox.html#removeItem">removeItem</a>()
and all items can be removed with <a href="qcombobox.html#clear">clear</a>(). The text of the current item is
returned by <a href="qcombobox.html#currentText-prop">currentText</a>(), and the text
of a numbered item is returned with <a class="compat" href="qcombobox-qt3.html#text">text</a>(). The current
item can be set with <a href="qcombobox.html#currentIndex-prop">setCurrentIndex</a>(). The
number of items in the combobox is returned by <a href="qcombobox.html#count-prop">count</a>(); the maximum number of
items can be set with <a href="qcombobox.html#maxCount-prop">setMaxCount</a>(). You can allow
editing using <a href="qcombobox.html#editable-prop">setEditable</a>(). For editable
comboboxes you can set auto-completion using <a href="qcombobox.html#setCompleter">setCompleter</a>() and whether or not
the user can add duplicates is set with <a href="qcombobox.html#duplicatesEnabled-prop">setDuplicatesEnabled</a>().</p>
<p>QComboBox uses the <a href="model-view-programming.html">model/view framework</a> for its
popup list and to store its items. By default a <a href="qstandarditemmodel.html">QStandardItemModel</a> stores the items
and a <a href="qlistview.html">QListView</a> subclass displays the
popuplist. You can access the model and view directly (with
<a href="qcombobox.html#model">model</a>() and <a href="qcombobox.html#view">view</a>()), but QComboBox also provides
functions to set and get item data (e.g., <a href="qcombobox.html#setItemData">setItemData</a>() and <a href="qcombobox.html#itemText">itemText</a>()). You can also set a new
model and view (with <a href="qcombobox.html#setModel">setModel</a>() and <a href="qcombobox.html#setView">setView</a>()). For the text and icon in
the combobox label, the data in the model that has the <a href="qt.html#ItemDataRole-enum">Qt.DisplayRole</a> and <a href="qt.html#ItemDataRole-enum">Qt.DecorationRole</a> is used. Note
that you cannot alter the <a href="qabstractitemview.html#SelectionMode-enum">SelectionMode</a> of
the <a href="qcombobox.html#view">view</a>(), e.g., by using
<a href="qabstractitemview.html#selectionMode-prop">setSelectionMode()</a>.</p>
